摘要
甘肃省阿克塞哈萨克族自治县的哈族、汉族居住地水源氟浓度为０．３２ｍｇ／Ｌ，０．３９ｍｇ／Ｌ，但哈族居民每日通过饮用砖茶熬制的奶茶，其日总摄氟量达到了少儿６．０４６ｍｇ，成人８．９４８ｍｇ，当地汉族居民春、夏、秋季饮用普通花茶日总摄氟量少儿０．９６２ｍｇ，成人１．８１９ｍｇ。大量的茶氟摄入导致哈族８～１５岁少年儿童和成人氟斑牙患病率达到８４．２％和９３．３３％，氟斑牙指数分别为３．０５和４．２５，属氟中毒重度流行人群。哈族奶茶与汉族冬季饮用的砖茶与氟中毒反应呈明显的相关性（ｒ＝０．９９，ｒ＝０．９６）。
The water fluorine concentrations
were 0.32mg/L and 0.39 mg/L in the hasake and Han Living areas at
Akesa Hasake minority Autonomy County,Gansu Province.Hasake
inhabitants` total fluorine intake was 6.046 mg(children) and 8.948
mg (adults) every day by the way of drinking milk tea which made from
brick tea water.Han inhabitants` total fluorine intake was 0.962 mg
(children) and 1.819 mg (adults) every day by drinking ordinary
flower tea at spring,summer and autumn,however,at winter,they drank
brick tea .Their total fluorine intake was 2.492 mg (children or
adults).Because of over intake of tea fluorine,the dental fluorosis
prevalence of Hasake 8 to 15 years old children and adults was 84.42%
and 93.33%,and the indexes of dental fluorosis were 3.05 and
4.25.This population to severe fluorosis people.The investigation
show:the dental fluorosis prevalence of Han children and adults was
25% and 38.39%,and the indexes of dental fluorosis were 0.70 and
1.30.They belonged to moderate fluorosis epidemic people.The
statistic analysis show:the milk tea drank by Hasake and the brick
tea drank by Han at winter had significant correlation with
fluorosis(r=0.99,r=0.96).
